Callum Fraser’s games are totally awesome but when his
Rubidium Time-Leap flips Aran Bruce and his best friends—Brian and Fianna Fraser—back
to AD 210, the reality is incredible. They have a task list to fulfil, which
includes solving a local mystery, but it’s a nightmarish business when Ancient
Roman Emperor Severus and his legions heap death and destruction on the Taexali
Celts of northern Britannia.

Giving help to Celts and Romans alike becomes a lethal
assignment—some Celtic chiefs are as foul as Severus and his beastly son
Caracalla. Dicing with death becomes the norm for the time travellers from
Kintore, Aberdeenshire.
